Oekaki (お絵描き) is a Japanese term to describe the act of doodling, especially computer "doodles" and/or "scribbles," and a kind of imageboard system that revolves around creating such style of computer art.

An Oekaki image board allows any contributor to create art on it using a Java applet on their computers. Two of better known systems are called OekakiBBS and PaintBBS. These systems have become more and more sophisticated over time, allowing the quality of the pictures on the boards to increase.

The board system allows users to browse, rate, and comment about posted art. Sometimes, the software will also include a replay option.

Oekaki chat, or paint chat, is a type of online drawing application and service that has similar drawing functionality with an Oekaki image board, but where users can talk to each other and draw collaboratively.

Probably the most well known Oekaki board in furry is the Bluefurry Oekaki board at Bluefurry.com, administered by furry artistGuppy, and running on a modified PaintBBS system. Perhaps the most advanced furry Oekaki boards out there are Coonikaki and Deep Thinkin' Perverts, both run on the same website. Deep Thinkin' Perverts tends to contain more adult content than Coonikaki while both have mature content.
